The MIT525 5 kV insulation resistance tester is a CAT IV rated, compact tester for the diagnostic testing and maintenance of high voltage electrical equipment. Enclosed in a tough case, it is both smaller and lighter than its predecessor making it even easier to carry and store. The MIT525 comes with all test modes including a ramp test plus advanced memory functions with recall to screen, RTC for time/date stamp of results, and USB drive to PC/PowerDB.

As well as measuring insulation resitance to 20 TΩ, the MIT525 also offers various diagnostic tests such as polarisation index, dielectric absorption ratio, step voltage, dielectric discharge, and ramp testing.

The MIT525 is also equipped with lithium-ion fast rechargeable batteries and has a large, clear, easy-to-read, display making it equally suitable for use in both bright sunlight and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status, and time constant. In addition, the elapsed time of the test is displayed constantly, removing the need for separate timer. 

The MIT525 is fully compatible with CertSuite Asset, our cloud-based system that uploads all your valuable test results as they are recorded, securely storing them for future use, and builds a graph and a report during the test. All asset and test records can be accessed simultaneously by multiple users (one licence required per user).
